Abstract: A common communications protocol is described among devices in a unified communications network. Native devices receive upstream commands and forward them to downstream devices without interpreting the commands. The native devices reformat commands intended for mapped devices in the unified communications network. The common communications protocol calls for left shifting address fields for transmitted commands until the command arrives at its intended destination.

Abstract: Systems and methods for contextual audio switching for a USB controlled audio device coupled to a processor-based host are presented. Two or more USB audio endpoints associated with a singular output audio transducer or transducer set are declared at the USB controlled audio device. The two or more USB audio endpoints are monitored to identify an audio signal presence at the two or more USB audio endpoints. A priority audio signal may be determined responsive to identifying the audio signal presence at two or more USB audio endpoints.

Abstract: Systems and methods for Bluetooth Control for VoIP telephony using the Bluetooth Headset Profile are presented. A Bluetooth Headset Profile volume control command message is received and translated to a corresponding USB HID profile menu up or menu down command message. A Bluetooth Headset Profile hookswitch command message is received and translated to a USB HID profile menu item select command message.

Abstract: An improved surgical tool of the type comprising handle means having a movable tool-operating handle member, a tool head having first and second tissue-engaging members movable between open and closed positions relative to one another, and means coupling the tool head to the handle means for causing opening and closing movement of the tissue-engaging members in response to manipulation of the movable tool-operating handle member. The improved tool is characterized by an inner shaft secured to a stationary part of the handle means, and a hollow outer shaft disposed in telescoping relation to the inner shaft, with the tool head being secured to the inner shaft and the outer shaft being movable axially relative to the inner shaft by manipulation of the movable tool-operating handle member, with the outer shaft causing opening and closing of the tissue-engaging members as it undergoes telescoping movement.
